- Intervention effect Biochar improved soil water content.
- Intervention effect Biochar increased soil pH.
- Intervention effect Biochar enhanced soil organic carbon content.
- Intervention effect Concentrations of NH4+-N and NO3−-N generally decreased across all treatments compared with their controls.
- Association Winter wheat yield was positively correlated with biochar application at 10 and 20 t ha−1, without statistically significant differences.
- Association Winter wheat yield was positively correlated with N levels of 140 and 210 kg N ha−1, without statistically significant differences.
- Observation The positive effects of biochar on soil properties and yield declined over time.
- Observation No significant winter wheat yield differences were observed 7 years after the initial biochar application and 3 years after reapplication.
